With the various kinds of transformers available in the market, each supporting different applications, power transformers in India are the most popular types of transformers used. These transformers are highly efficient in transmitting high voltage levels at loads above 33kv. In fact, they perform their best at 100% load! This quality of providing maximum efficiency has resulted in power transformers being used in transmission networks, transmission substations, and power generation stations. These power transformers are further categorized into step-up and step-down transformers to increase or decrease the voltage levels as required.
While earlier agriculture had everything done manually, today it has transformed into a high-tech sector with a variety of magnetic being used for farming, tilling, and harvesting. One of the equipment that helps in a major way in this industry is the transformer. These equipment are designed to provide sufficient power to support various agricultural applications. There are various types of transformers available in the market, out of which three are majorly used in the agricultural industry, namely power transformers, auto transformers, and high voltage transformers.
What are auto-transformers?
Auto transformers are electrical transformers having only a single winding; thus the single coil acting alone, without any kind of automatic mechanism like in other transformers. In fact, the single coil itself plays the role of both primary and secondary winding’s, with one end acting as primary, and the other end acting as the secondary. In this way, auto-transformers have the benefit of being smaller, lighter, and cheaper than other double winding transformers; but with the disadvantage of not providing isolation between the primary and secondary circuits.
As the name suggests, insulators are used to insulate electrically charged part of an equipment from another charged or uncharged metal part. Insulators cover the conductor and act as a barrier to keep the conductors unreachable, when used in lower utilization voltage. And, in high voltage overhead transmission and distribution, insulators are used to insulate the live conductor from transmission towers or poles.
Electricity is produced at very high voltages in power grids, and this voltage varies from country to country; and in fact, it also varies between regions within a single country. But, however it may vary, the produced electricity is not fit for being used directly into homes, offices, and factories. The high power of electricity produced will explode the appliances used, and cause extreme risk to the end users. This is where transformers come to the rescue.
